True.

It's easier to upgrade user agents than get everyone to put visible 
"skip
navigation" or "skip to main content" links on their pages.

In fact, most browsers now could quite easily support <section> and <h>.
<nl> is harder to do, because the browsers aren't looking for href 
attributes
on <li> elements, but even that isn't such a stretch to picture being
implemented.

But let's talk about HTML 2.0.  You seem to think that browsers aren't
properly implementing the <link> attribute as defined by HTML 2.0 -- 
well,
here's what it says:

   Link:  LINK

   The LINK element represents a hyperlink (see section Hyperlinks).  Any
   number of LINK elements may occur in the HEAD element of an HTML
   document.  It has the same attributes as the A element (see section
   Anchor:  A).

   The LINK element is typically used to indicate authorship, related
   indexes and glossaries, older or more recent versions, document
   hierarchy, associated resources such as style sheets, etc.

The problem with browsers "not implementing <link>" is that it is vague
on how to present this metadata.  Neither HTML 2.0, nor 3.2, nor 4.0,
nor 4.01, nor XHTML 1.0 specifies what it means to use <link>.  Should
this be presented as a menu?  In a pop-menu with page information?
Should it be visible content?

The closest that you get to this is a vague suggestion in HTML 4.0:
"Although LINK has no content, it conveys relationship information
that may be rendered by user agents in a variety of ways (e.g., a
tool-bar with a drop-down menu of links)."

Note the word "may," BTW.

It's still a hack, because the only reason the link exists is to 
overcome
a structural deficiency in HTML.

There's a difference between a set of links designed to take you through
the document, and one which is designed to take to, well, where you
appear to be now, which was only inserted for supposed compatibility 
with
screenreaders and other linear forms of access.

We'd be much better off with a robust markup language instead of HTML
which requires literally telling, in a way that _varies from site to
site to site_, where the primary content is located and where the 
navigation
links are.
